These two are from my collection, both quite old so may be difficult to get hold of except through a library.
1. Hostage in Peking, by English journalist Anthony Grey.
I read it while convalescing from an operation in the early Seventies and it kept me absorbed but horrified during this period. It covers Grey's 2 years in solitary confinement in a Chinese jail during Mao's Cultural Revolution, an imprisonment which received widespread condemnation at home. Based on secret diaries he smuggled out on his release.
2. Wake Up It's a Crash by Earl Moorhouse.
Written by a survivor of the first 747 disaster, it covers the event and his escape (with his wife and two sons) from the burning aircraft which crashed shortly after takeoff in Nairobi. 98 survived, 59 were killed. One to save for the Departure Lounge possibly !
